The typical power is measured with following transition from horizontal 3 scale pattern to vertical3 scale pattern.2. The deep sleep power is the consumed power when the panel controller is in deep sleep mode. 3. The listed electrical/optical characteristics are only guaranteed under the controller & waveformprovided by DKE.4.
